+Date: Mon, 14 Jan 2013 01:39:10 +0000
+Subject: ntpd: fix incorrect m_status field in outgoing packets. Closes 5120
+
+When using busybox ntpd with an NTPv3 client and NTPv4 server (or vice
+versa), the version numbers can be incorrectly ORed together, yielding
+the bogus value of "NTPv7".  This makes ntpd unusable with clients
+such as Chrony and Windows "Internet Time".
+
+This patch avoids the version mangling, by copying only the Leap
+Indicator bits from the server's status field.
